Novel mechanical connecting device for precast pile
The invention relates to a novel mechanical connecting device for a precast pile. The novel mechanical connecting device comprises a steel bar, a sleeve, a spring, a gasket, a clamping piece, an external nut and an inserting rod. The steel bar comprises an upper steel bar and a lower steel bar; a through hole is formed in the external nut; the external nut comprises an upper external nut and a lower external nut; the sleeve is fixedly connected with the upper external nut; the upper steel bar is fixedly connected with the upper external nut through the sleeve; the spring, the gasket and the clamping piece are sequentially arranged at the lower end of the upper steel bar from top to bottom; the lower steel bar is connected with the lower external nut; and the lower end of the inserting rod is connected with the upper end of the lower external nut. By arranging the steel bar, the inserting rod and the sleeve, the anti-pressure capability of the novel mechanical connecting device is enhanced, the working stability of the novel mechanical connecting device is guaranteed through the connection effect of the sleeve and the upper external nut, the service life is prolonged, and installation is convenient, fast and effective.
本发明涉及一种用于预制桩的新型机械连接装置，包括：钢棒，套筒，弹簧，垫片，卡片，外接螺母，插杆；所述钢棒包括上钢棒，下钢棒；所述外接螺母内设有通孔；所述外接螺母包括上外接螺母，下外接螺母；所述套筒与所述上外接螺母连接固定；所述上钢棒通过所述套筒与所述上外接螺母连接固定；所述弹簧、垫片、卡片按由上至下的顺序依次设置在所述上钢棒的下端；所述下钢棒与所述下外接螺母连接；所述插杆的下端与所述下外接螺母的上端连接。本发明通过钢棒、插杆及套筒的设计，增强了其抗压能力，并且套筒与上外接螺母连接的效果，保证了其工作的稳定性，增强了使用寿命，且安装便捷有效。
